Description
This contribution contains the first numerical computation of the complete set of relativistic corrections of relative order u2 for electric dipole (E1) transitions in heavy quarkonium; in particular, for the processes χbJ(1P) → Γ(1S) + γ with J = 0, 1, 2. We assume that the momentum transfer of the heavy mesons involved in the reactions lies in the weak-coupling regime of the low-energy effective field theory potential nonrelativistic QCD (pNRQCD) and thus a full perturbative calculation can be performed.
